Fractional CO2 Versus Radiofrequency as Hair Regrowth Enhancers for Female Androgenic Alopecia: A Randomized Controlled Trial

This study found that combining fractional CO2 laser treatment with platelet-rich plasma led to a statistically significant improvement in hair regrowth for male androgenetic alopecia, compared to using the laser treatment alone.

This pilot study reported significant improvement in hair restoration and patient satisfaction with the use of fractional carbon dioxide laser followed by platelet-rich plasma, showing greater hair density increases using higher laser pulse energy settings in individuals with androgenetic alopecia.

In this study, a specially adapted nonablative radiofrequency device significantly increased hair growth measures in most patients with androgenetic alopecia, including hair count and density.

This guideline summarizes evidence-based and expert-based recommendations for treating androgenetic alopecia, adapted by an Italian expert group in alignment with Italian pharmacological policies.

This study found that using a fractional CO2 laser in combination with minoxidil significantly increased hair count and thickness in Egyptian men with androgenetic alopecia.

This study found that the treatment group experienced a higher average increase in hair counts than the placebo group, but the difference was not statistically significant.

This study found that combining fractional radiofrequency microneedling with 5% topical minoxidil improved hair count and thickness more than minoxidil alone in Chinese men with male pattern hair loss.

This guideline review by the European Dermatology Forum evaluates current treatments for androgenetic alopecia but reports no new research findings, aiming to assist dermatologists in selecting safe and effective therapies.

This study found that combining ablative fractional CO₂ laser therapy with hair growth factors significantly increased hair density in men with androgenetic alopecia compared to using growth factors alone.

This study concluded that ablative fractional lasers may induce hair regrowth in mice by activating the Wnt/β-catenin pathway.

In this study, the researchers found that the effectiveness of a 1,550-nm fractional laser in promoting hair growth in mice depends on the specific combination of beam energy and density, with inappropriate settings potentially causing ulcers or hair follicle injury.

This review discusses the development of an algorithmic guideline for treating androgenetic alopecia in Asian patients, using the BASP classification to address limitations of previous guidelines, and reports no clinical results.

This review discusses various treatments for androgenetic alopecia, including minoxidil, finasteride, dutasteride, ketoconazole, and experimental options, but reports limited clinical trial evidence for efficacy.

PGD2 stops hair growth and is higher in bald men with AGA.

This study found that treatment with a 1550 nm fractional erbium–glass laser increased hair density and thickness in women with female pattern hair loss, suggesting it may be an effective and safe option.

This study found that a once-daily 5% minoxidil topical foam is as effective as a twice-daily 2% minoxidil topical solution for hair growth in women with androgenetic alopecia, with fewer side effects and greater styling convenience.

This review discusses the shedding phase of the hair cycle, known as exogen, and reports no new findings while analyzing related processes like club fiber formation and release.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

Minoxidil 5% solution quickly improves hair growth and density with minimal side effects.

This paper discusses key mechanisms of androgen metabolism in androgenetic alopecia and reports the effectiveness of treatments like oral finasteride and topical minoxidil, highlighting the limited success rate due to factors like follicular inflammation.

This study describes the kenogen phase, where hair follicles rest after shedding, and finds its duration and frequency are greater in individuals with androgenetic alopecia, potentially contributing to baldness.

Female and male AGA are different diseases.

This article proposes five different mechanisms for telogen effluvium, supported by clinical findings, based on changes in different phases of the hair cycle.
